Our eEF2K (Ser-398) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects human, mouse, and rat eEF2K (Ser-398) and is antigen affinity purified. It is great for use in WB.

Western blot image of human Jurkat cells treated with calyculin A (100 nM) for 30 min. (lanes 1-6), then some lanes of the blot were treated with lambda phosphatase (lanes 2, 4 & 6). The blot was probed with rabbit polyclonals anti-eEF2K (C-terminus) (lanes 1 & 2), anti-eEF2K (Ser-445) phospho-specific (lanes 3 & 4), and anti-eEF2K (Ser-398) phospho-specific (lanes 5 & 6).

Target

eEF2K (Ser-398)

Target Description

Eukaryotic elongation factor 2 (eEF2) catalyzes the translocation of peptidyl-tRNA from the A site to the P site on the ribosome. eEF2 kinase (eEF2K) phosphorylates and inactivates eEF2, resulting in the inhibition of peptide-chain elongation. eEF2K is normally dependent on Ca2+ ions and calmodulin, and can be activated by PKA in response to elevated cAMP levels during cell stress- or starvation-related conditions. Regulation of eEF2K occurs through phosphorylation at multiple sites. Ser-78 phosphorylation is required for calmodulin binding and eEF2K activity, while phosphorylation of Ser-500 is required for Ca2+/calmodulin-independent kinase activity. Thr-348 is an autophosphorylation site that is required for kinase activity. Inhibitory phosphorylation may also regulate eEF2K, since phosphorylation at Ser-359 by SAPK4/p38δ causes inactivation of eEF2K. Thus, multisite phospho-regulation of eEF2K may be important for proper control of eEF2K activity and protein translation.

Antigen

Phospho-eEF2K (Ser-398) synthetic peptide (coupled to carrier protein) corresponds to amino acids surrounding Ser-398 in human eEF2K. This sequence is well conserved in rat and mouse eEF2K, and has low homology to other proteins.

Species Reactivity

Human, Mouse, Rat

Storage

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Physical State

Liquid

Buffer

PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol

Dilution Ranges

WB: 1:1000

Conjugate

Unconjugated

Specificity

The antibody was cross adsorbed to unphosphorylated eEF2K (Ser-398) peptide before affinity purification using phospho-eEF2K (Ser-398) peptide (without carrier). This antibody detects a 105 kDa* protein corresponding to the molecular mass of eEF2K on SDS-PAGE immunoblots of Jurkat cells treated with Calyculin A, and this reactivity is removed after lambda phosphatase treatment.
